x86, mem: memmove_64.S: Optimize memmove by enhanced REP MOVSB/STOSB Support memmove() by enhanced rep movsb. On processors supporting enhanced REP MOVSB/STOSB, the alternative memmove() function using enhanced rep movsb overrides the original function. The patch doesn't change the backward memmove case to use enhanced rep movsb.
